Scientists shatter distance record for teleporting quantum data

Posted by in categories: computing, encryption, internet, quantum physics

Quantum teleportation, the act of reconstructing quantum data somewhere else, is impressive just by itself. However, scientists at the US’ National Institute of Standards and Technology have managed to one-up that feat. They’ve broken the distance record for quantum teleportation by transferring the information from one photon to another across 63 miles of optical fiber. That may not sound like much, but it’s an achievement just to beam that data in the first place — 99 percent of photons would never make the complete trip. It was only possible thanks to newer detectors that could pick up the faint signal of the lone light particle.

You’d clearly need to send much more information before this teleportation becomes practical, but the achievement does open the door to many possibilities in quantum computing. You could use unbreakable quantum encryption at inter-city distances, for instance. The biggest challenge may simply be to extend the range to the point where quantum data transfers work on the scale of the internet, where there are occasionally thousands of miles between connections.

Shades of ‘Star Trek’? Quantum Teleportation Sets Distance Record

Posted by in categories: encryption, internet, quantum physics

You’ve gotta love Star Trek, but there is absolutely NO WAY I’d ever set foot in a real teleportation device! (if one ever really got made, of course) Call me crazy, but I’m kinda partial to keeping my molecular cohesion as intact as possible, which kinda rules out having it ripped apart and remade on the other side.


A record-breaking distance has been achieved in the bizarre world of quantum teleportation, scientists say.

The scientists teleported photons (packets of light) across a spool of fiber optics 63 miles (102 kilometers) long, four times farther than the previous record. This research could one day lead to a “quantum Internet” that offers next-generation encryption, the scientists said.

Researchers enable robots to see through solid walls with Wi-Fi (w/ Video)

Posted by in categories: internet, materials, mobile phones, robotics/AI

(Phys.org) —Wi-Fi makes all kinds of things possible. We can send and receive messages, make phone calls, browse the Internet, even play games with people who are miles away, all without the cords and wires to tie us down. At UC Santa Barbara, researchers are now using this versatile, everyday signal to do something different and powerful: looking through solid walls and seeing every square inch of what’s on the other side. Built into robots, the technology has far-reaching possibilities.

“This is an exciting time to be doing this kind of research,” said Yasamin Mostofi, professor of electrical and computer engineering at UCSB. For the past few years, she and her team have been busy realizing this X-ray vision, enabling robots to see objects and humans behind thick walls through the use of radio frequency signals. The patented allows users to see the space on the other side and identify not only the presence of occluded objects, but also their position and geometry, without any of the area. Additionally, it has the potential to classify the material type of each occluded object such as human, metal or wood.

The combination of and automated mobility can make these robots useful in situations where human access is difficult or risky, and the ability to determine what is in a given occluded area is important, such as search and rescue operations for natural or man-made disasters.

The world’s first all-electric propulsion satellite is now operational

Posted by in categories: electronics, internet, space

Boeing has announced that the ABS–3A, the world’s first all-electric propulsion satellite, has commenced its tour of duty.

The communications satellite is being operated by ABS, a Bermuda-based satellite network that provides TV, Internet, and cellular services across the world. Unlike conventional satellites, which have mostly used propellant systems that burn chemicals of one kind or another to get about the place, the ABS–3A makes use of a xenon-ion propulsion system to achieve thrust.

Specifically, the all-electric propulsion system uses electron bombardment to create xenon ions, which are then expelled by the spacecraft, producing thrust in the opposite direction.

Swarms of smart nano-satellites may offer global connectivity (With video)

Posted by in category: internet

One day we may have global connectivity — even in the remotest parts of the world — thanks to teams of tiny, intelligent, swarming satellites called CubeSats.

In an industry that doesn’t like change and definitely doesn’t like to rely on the latest and greatest in technology, CubeSats appear to be changing the game for the space industry.

And one of the things these cube-shaped satellites could be changing in the next 10 years is how to help people in impoverished or remote parts of the world get long-sought Internet access.

How 5G will Power the Future Internet of Things

Posted by in categories: internet, mobile phones, transportation

At Intel Developer Forum in San Francisco August 18th – 20th, two Intel executives discuss how 5G network capabilities will transform the way we live.

Imagine taking a trip to a cabin in the woods to get some work done and have a mini-vacation. Today, given our need for wireless connection, that’s a sketchy proposition.

You’ve got GPS in your rental car, plus your laptop, your smartphone, maybe a tablet or a smartwatch. But what if there’s no cable? What if there’s no Wi-Fi connection? What if the cellular connection is weak?
